AUTOMATIC LIQUID-DRAWING DEVICE.

SPECIFICATION forming part of Letters Patent No. 309,219, dated DecemberApplication filed January 2S, 1884. (No model.)

.To all whom, it may concern/.-

Be it known that I, VILLIAM HENRY Fatima a citizen of the United States,and a resident of Minneapolis, in the county of Hennepin, in the Stateof Minnesota, have invented certain new and useful Improvements inAutomatic Liquid-Drawing Devices, of which the following specificationis a full, clear, and exact description, reference being also had to theaccompanying drawings, in which- Figure 1 is a semi-sectional side view,and Fig. 2 is a semi-sectional front view. Fig. 3 is an enlargedperspectivev view of the valvecasing. Fig. 4. is an enlarged perspectiveview of the valve. Fig. 5 is an enlarged sectional side view, and Fig. 6is an enlarged plan view, of thevalvecasing and its actuating mechanism.Fig. 7 shows detached perspective views of the valve and its actuatingmechanism. Fig. 8 is a sectional side view of a portion of the casingand reservoir, illustrating the manner of arranging and constructing theautomatic coin-chuteclosing mechanism. Fig. 9 is a view of thecoin-chute-closing slide.

A is an outer casing or frame, made in the form of a building, with thetop or roof B adapted to be removed, and with two recesses, C C2, in theform of doorways7 or vestibules, formed in its front, as shown. In thelower part of each of the vestibules steps D D2 are arranged, the step Dhaving a recess in its top to receive a drinking glass or cup, E, andthe back part of the vestibule C2 provided with a slot, c, through whichsmall coin may be passed, as hereinafter shown.

F is a tank or reservoir suspended inthe upper part of the casing A, andhaving a long tube, G, leading downward therefrom, the

latter supplied with a smaller tube, H, at

right angles to it, near its lower end.

his a still smaller tubeleadin g from the under side of Vthe tube H outthrough the back of the vestibule C', and ending above the vessel E, asshown. The inner end of the tube H is provided with radiating ports b',adapted to be covered with a disk-valve, c, having corresponding ports,b2. A valve-stem, d', leads from the valve c through the center of theinner end of the tube H and out through the other end of the saine. Uponthe outer end of the valvestem el is secured a cross-bar, d2, havingslots l in its ends, in which the bent ends of another cross-bar, di,fit, the latter being mounted upon a small shaft, (1*, supported by itsends in a frame or hanger, d5, secured to the pipe hy or to the frame orcasing A. Upon this small shaft d, outside of the bar cl3, is secured alever consisting of a long arm, K, and short arm K2. By this arrangementthe valve c and its stem will be left free to move endwise iudependentof the lever K K2, while -at the same time, by means of the ends of thecrossbar d3 iitting into the slots in the ends of the bar di, thevalve-stem will be oscillated by the upward 'and downward `movement ofthe lever to open and close the valve c. This is a very importantfeature of my invention, as it prevents the friction or weight of thelever from preventing the perfect seating of the valve. Upon the end ofthe long arm K of the lever is a small disk or trough, c, and upon theother or short arm is secured by a piston-rod, g, a piston-head, g2,moving up and down with a cylinder,M, filled with water or other liquid.The trough c, when the long arm K is raised upward, as shown in Figs. land 2, will come directly beneath thc inner end of a small chute, a2,leading from the slot a, so that a coin dropped through the slot will becarried by the chute into the trough e, as hereinafter shown. llhe valvec will be so constructed Jthat when the long arm K is at its highestpoint the valve will be closed, and will be wide open when the same armis at or near itslowest point, and the ports b bl will be so graduatedas to size that enough liquid will pass through them to fill the vesselE while the lever K KZ is moving downward and upward again one fullstroke within a certain Y time, as hereinafter explained. Small movableweights g will be attached to the lever, it being necessary to theproper aotion of the lever that the short arm K2 and its attached partsshould be heavier than the long arm Kwhen the trough c is empty, whileat the same time it must be so delicately poised that the weight of asmall coin will overcome the eXtra weight of the short arm and move thelong arm downward until the inclination of the trough will cause thecoin to slide off.

This device is intended to be usedmore particularly in drawing mineralwaters, 5to.; but

the pistonrod g', to regulate the movement of IOO may be used in drawingnearly any kind of liquids.

The lever K K2 may be adjusted by the small weights g3 to adapt it to beoperated by any desired value of coin, but usually adapted to beoperated by one single cent. Beingthus adj usted, when a cent is droppedthrough the slot a it will fall into the trough e and cause the lever Kto fall. The lever will fall until the inclination of the trough issufficient to cause the cent to drop off, and thus open the valve c andallow the liquid to run into the glass E. Then the short armK2, beingheavier without the cent than the long arm, will fall again and closethe valve.

In Figs. 8 and 9 is shown the mechanism for automatically closing theslot a' when the liquid in the reservoir is exhausted, so that no coinscan be passed through the slot except when the reservoir is suppliedwith liquid. This mechanism consists of a float, N, resting in theliquid in the reservoir F, and having a cord, t", attached to it andpassing up over a pulley, 2, on the top of the reservoir and downoutside the reservoir through an eye in one end of a small lever, P,pivoted tothe casing A and ending in a ball or enlargement, is, asshown. The other end of the lever P is connected by a rod, t, to aslide, It, adapted to rise and fall behind the slot a', to open or closeit. The cord z" runs freely up and down through the eye on the lever P,when the iioat N rises and falls with the varying height of the liquidin the reservoir without affecting the lever, except when the liquid inthe reservoir is so nearly exhausted as to cause `the float to fall solow as to raise the ball or enlargement i3 far enough to strike thelever P and close the slide, the lever P thus being actuated only whenthe liquid is exhausted from the reservoir. By this means the coin-slidewill be closed when the liquid is exhausted from the reservoir, therebyavoiding the danger of the dropping of coins into the slot when noreturns of liquid can be had for it.

I do not wish to confine myself to this precisemethod of connecting thefioat N and slide or door R, as I am aware that many simple devices maybe used for that purpose. The piston g2, rising and falling in theliquid in the cylinder, acts as a brake to the lever, and causes it tomove slowly up and down, and thereby hold the valve c open much longerthan it would be held otherwise. By increasing or decreasing thediameter of the pistonhead, so as to leave a greater or less spacebetween its edges and the sides of the cylinder, it will move withgreater or less speed through the liquid. The less space there isbetween the piston -head and the cylinder the more the lever K K2 ismaking one full stroke, or

during the time the cent in the trough is moving the arm K downward anduntil the lever returns to its former position.

Another important feature of my invention is the long tube G, by which Iam enabled to always secure a nearly uniform head'7 of liquid above thevalve e, and thereby secure a more even flow than could be otherwiseobtained.

Having described my invention and set forth its merits, what I claimis- 1. The combination of the reservoir F, having the discharge-tubes G,H, and h, valve c, lever K K2, pivoted to and adapted to open and closesaid valve, trough e, piston-rod g, piston-head g2, and cylinder M,substantially as and for the purpose set forth.

2. A casing, A, having recess C', adapted to support a 'drinking-vessel,recess C2, provided with coin-slot a', areservoir for lholding liquids,discharge-tubes G, H, and h, leading from said reservoir and providedwith valve e, and means, substantially as described, for

.opening and closing said valve.

3'. A reservoir for holding liquids, a discharge-pipe leading from saidreservoir and provided with a valve, a lever adapted to open and closesaid valve, means for moving said lever, and a piston attached to saidlever and moving in liquid simultaneously with said valve and lever,substantially as and for the purpose set forth. l

. 4. In an automatic liquid-drawing device, and in connection with theco-operative parts thereof, the combination of a casing, A, providedwith acoin-slot, a', a reservoir, F, a

IOO

iioat, N, within said reservoir, a slide, R, and

means for connecting said iioat with said slide, whereby the exhaustionof the liquid in said reservoir will cause said slide to cover and closesaid coin-slot, substantially as set forth.

In testimony whereof I havehereunto set my hand in presence of twosubscribing Witnesses.
